Looking for suggestions....I have seen MN loves Efteling in Holland but wonder whether 12yo would be too old for this?
Ideally looking for something in UK, but Europe would be ok too....
Ideas I've already had are: Portsmouth (Historic Dockyard) - and New Forest; Snowdonia National Park (outdoor pursuits). Lake District (ditto).
We already do/have done Devon & Cornwall a lot so looking elsewhere in the UK.
